According to analysts from Gartner and elsewhere, every enterprise with a significant cloud presence needs a cloud access security broker to protect cloud-based data. CASB products can sit either on-premises or live in the cloud, but they all have the same basic function – providing a secure gateway for data traveling to and from the cloud, particularly with respect to SaaS applications and common cloud storage services like Box or Dropbox.
CASB products provide a variety of security measures, including access control, firewall, identity management, anti-malware, DLP, encryption and threat management.
